分子生物学分子生物学
牙科研究牙科研究

背景情况:

肺炎是一种由细菌引起的炎症性疾病,导致严重的疼痛和降低生活质量.
微RNA-455-3p (miR-455-3p) 涉及各种疾病,但其在脉炎中的作用尚不清楚.

研究的目的:

为了确定一个新的生物标志物用于脉炎诊断.
阐明涉及miR-455-3p的皮底层分子机制.

主要方法:

定量实时PCR (qRT-PCR) 用于测量miR-455-3p和ACTG1水平.
双露西法酶记者测定以确认准.
细胞计数工具-8 (CCK-8) 试验用于增殖分析.
流细胞测量用于对细胞亡的评估.

主要成果:

在肺炎患者的血清和组织中,miR-455-3p水平显著下降.
对ROC曲线的分析表明,在脉炎中,miR-455-3p的诊断性能很好.
试验室研究显示,miR-455-3p水平与LPS度和治疗时间相反相关,LPS抑制增殖.
上调的miR-455-3p促进了增殖和抑制了亡,而下调的miR-455-3p则产生了相反的效果.
鉴定出ACTG1是miR-455-3p的直接标,被它负面调节. 上调的miR-455-3p抵消了LPS诱导的效应,这种效应被ACTG1过度表达所逆转.

Mechanism of Angiogenesis

Mechanism of Angiogenesis

Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

Regulation of Angiogenesis and Blood Supply

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...

TGF - β Signaling Pathway

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
